Re: Installing Camber tops

Yeah i'm quite sure Noltec make the 2 kinds, one uses polyurahane around the spherical bearing in the top (spelling), then they make a more race orientated one without the polyurahane and supposedly more adjustment.

I dont think they would make adjustable lower control arms, but you dont need to either! Its quite easy to fit Sigma control arms, or I think its one of the MX cressidas have longer arms. FYI RA28 arms, along with AE86, are 300mm long.

With a 35mm RCA fitted and wanting neg camber, you definately need to extend the control arm or get a different designed strut top to the Noltec item (and by sounds of it kmac item) that I have. So 2 options there really. I'm going to be moving the pivot point out of my control arm (not extending it so to speak) to get zero bump steer, but this is related to the rack n pinion swap. I'll be moving out each side 20mm which should give me plenty of neg camber with my current strut tops. Basically then the strut tops will just be for fine adjustment.

If you extend the control arm, you'd want a longer threaded shaft between the inner and outer tie rods.

The radius rod has a fair amount of adjustment for castor on it. I reckon this is enough, but Noltec can add more thread to it so you can run more castor again.

Don't see why a non-adjustable swaybar would cause any problems.

Any other questions just ask.. I've got the RA28 handling soooo much better now than what it ever has before. The AE86 used to always out-corner it but now the 28 is catching up quick Smile

Ah okay this is all very interesting..
So Noltec mite make a second top with greater-adjustment (~6mm), i mite email them and see if they still do and a price, and see if they even make adjustable lower control arms ..

If not, would a local engineers shop be able to make up something like this pretty easily?

So to really have control over your camber/castor/toe in the RA strut, With an 32-35mm RCA fitted, would be best to extend your lower control arms slightly, fit adjustable strut tops, am i right?
seeing id be getting a few new bits are there any other pieces in the front end that need to made be adjustable/or extended? custom tie-rods? will a non-adjustable swaybar pose a problem?(cant see why it would)

Im fitting a freshly rebuilt steering box soon to finish replacement of all the steering components, so im getting keen on the idea of going to the next stage with the suspension and get rid of bump steer..
plus I want that -camber! hehe

Thanks,
